No I don't convert anything like that, there is no such possibility I don't get any user from LDAP. All I do is search the LDAP Server for a user, if the ldap_use_lower_case is true, the user that searchs the LDAP server is transformed to lowercase. OpenMeetings itself will also use the lowercase username internally for that user if that option is set to true.
I cannot influence the way the ldap server itself compares the strings. Maybe there is an ignoreCase setting in the LDAP server. However, actually OpenMeetings does no string comparisson of Users and matches to results, its the other way round: The username is taken and an LDAP search is started with that username. Line 353 the ldap_search_base is defined with the specified user from the login. And in http://svn.apache.org/viewvc/incubator/openmeetings/trunk/singlewebapp/src/app/org/openmeetings/app/ldap/LdapAuthBase.java?view=markup Line 82 you can see how the user+pwd is send to LDAP to authentificate. I cannot find any "equals" method that compares LDAP user to usernames of OpenMeetings, as there is none.
